Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82678, here are decompositions:
- 59 + 82619 = 82678
- 107 + 82571 = 82678
- 149 + 82529 = 82678
- 179 + 82499 = 82678
- 191 + 82487 = 82678
- 257 + 82421 = 82678
- 317 + 82361 = 82678
- 461 + 82217 = 82678
Showing the first eight; more decompositions exist.
